Abstract: This disclosure describes an infrastructure management system and method for identifying risk potentials within the infrastructure or for the infrastructure. A dedicated sensor system for identifying risk potentials is provided within the infrastructure or for the infrastructure. A gateway (for example an interface) is configured to receive sensor values that originate from sensors of mobile devices that are temporarily located within the infrastructure or within a defined range (radius) from the infrastructure. A processing unit (for example a server) is configured to receive the sensor values that are reported by the dedicated sensor system and to receive the sensor values of the mobile devices that are provided by the gateway and further to analyze the received sensor values in order to identify risk potentials for the infrastructure or within the infrastructure.

Abstract: The sensor assembly comprises: a bowl shaped, namely at least sectionally dished, membrane, with a curved surface and an oppositely lying surface; and a sensor blade extending from curved surface of the membrane. The membrane is so formed that at least one region of the curved surface adjoining the sensor blade is convex. A sensor formed by means of such a sensor assembly and by means of a transducer element coupled therewith and serving for generating a sensor signal representing movements of the sensor blade changing as a function of time and/or deformations of the membrane changing as a function of time, or a measuring system formed by means of the sensor and a measuring electronics connected thereto, can be used for registering pressure fluctuations in a flowing fluid, such as, for instance, a 400 C hot steam, for instance, in order to measure a flow parameter of the fluid.

Abstract: In a sensor assembly, a deformation body has two oppositely lying surfaces, an outer edge segment and a sensor blade extending from a surface outward. A protective apparatus protects the deformation body from pressure surges or abrupt changes of temperature on its surface. The protective apparatus includes at least one plate, extending radially inwardly so that a cavity is formed, which accommodates a region of the sensor blade adjoining the deformation body and remote from the distal end of the sensor blade, forming a gap between the plate and sensor blade. A sensor formed by the sensor assembly and a transducer element coupled therewith can be used for registering pressure fluctuations in a flowing fluid, such as steam having a temperature of 400 C and/or, a pressure of greater than 140 bar in order to measure flow parameters of the fluid.

Abstract: A sensor assembly has a deformation body having two oppositely lying surfaces and an outer edge segment as well as a sensor blade extending from the surface to a distal end and having a left side, first lateral surface and a right side, second lateral surface. An overload protection apparatus protects the deformation body against plastic deformation and has a support stirrup led with lateral separation around the sensor blade and a first stop and a second stop located on opposite sides of the sensor blade. The stops are so arranged that an intermediate space formed therebetween receives only a portion of the sensor blade. The deformation body and the sensor blade are excitable to oscillate about a shared static resting position and to be moved in such a manner that the sensor blade executes pendulum-like movements elastically deforming the deformation body.
